The copy read prints two update lines (June 20 and October 22, 2024) and no issue date of its own. Anthropic's card index gives March 2024; that page is not a source of this record, so no first publication date is recorded. An Internet Archive capture of 2024-03-04 at an earlier address holds the original 42-page expression, which the cross-family check of 2026-11-04 retrieved; it prints no date that was quoted.
